With this breakdown, this set would work great to relabel the T25s into T1000 (think Hustler Casino, which as green $1000 chips!), and have a T-100 base with starting stacks of up to 40k for 20 people, or up to 80k for up to 10 people.
I'm thinking a small, custom, oval shaped-label could be made with a color match to cover up the "25" with a "1000" denom label.
